The per-primitive have their own separate section in the FS thread
payload, and are not considered when setting the mask in
3STATE_SBE's ConstantInterpolationEnable.
This is also consistent with what is done for brw_interp_reg().

We found out that some HW changes on Xe2 make the HW avoid reading the
blend state if we're using the null_rt bit in the extended descriptor.
Since the alpha_to_coverage bit resides in the blend state, that state
is ignored and writes are going through to the depth/stencil buffers.
Disable null_rt in the color outputs if the color outputs can affect
other outputs (through alpha_to_coverage & omask).
Fixes tests in this pattern on Xe2 :

We'll want to tune this setting based on other parameters.

The long names were originally meant to map to the HW encoding but
nowadays the actual encoding values depend on gfx version, whether
instruction is 3src, etc.
